Slow sync

Since upgrading to iTunes 9.1, my 3GS sync's very slowly. in excess of 10 minutes yesterday. It's JB and I'm running on a Windows PC. the JB still works fine. I've seen this on the first synch after an iTunes upgrade, but not as a recurring issue. Is anyone else experiencing similar or have suggestions? My next move may be an iTunes unistall/reinstall.

I'm getting exactly the same issues where I have updated on Windows 7 64bit to Itunes 9.1.0.79 and its the backing up of the Iphone is taking forever even the ones after the 1st sync. I've had to disable the iphone backup for the time being until apple akcnowledge there's a bug and then update Itunes.
